If you are planning (as myself) to go for the MSCE Desktop Infrastructure there is some core technologies that you need to be pretty familiar with.
* WDS 2012
* Configuration Manager 2012
* MDT 2012
* USMT 2012
* RDS + RemoteFX 2012
* WSUS 2012
* MAP 8
* App-V 5
* GPO
and how these solutions integrate with each other.
The exam is pretty much based around how to deliver a desktop or an application to the end-user with the technologies I mentioned above.
So here you will find some links to download and some resources I self-found useful
MDT 2012

MAP (Is pretty much a agentless monitoring solution to see the usage of specific applications and see if your infrastructure is ready for migrate to the cloud or new versions of Windows)
